METHOD FOR IDENTIFYING CELLS BASED ON DNA REPLICATION DOMAIN TIMING PROFILES - Methods for identifying and/or distinguishing a homogeneous population of cells based on their replication domain timing profile using high resolution genomic arrays or sequencing procedures are provided. These methods may be used to compare the replication timing profile for a population of cells to another replication timing profile(s), a replication timing fingerprint, and/or one or more informative segments of a replication timing fingerprint, which may be simultaneously or previously determined and/or contained in a database, to determine whether there is a match between them. Based on such information, the identity of the population of cells may be determined, or the identity of the population of cells may be distinguished from other populations of cells or cell types. Methods for determining a replication timing fingerprint for particular cell types are also provided.

CAPACITIVE ELECTRODE HAVING SEMICONDUCTOR LAYERS WITH AN INTERFACE OF SEPARATED GRAIN BOUNDARIES - The present invention relates to a structure of a capacitor, in particular using niobium pentoxide, of a semiconductor capacitor memory device. Since niobium pentoxide has a low crystallization temperature of 600° C. or less, niobium pentoxide can suppress the oxidation of a bottom electrode and a barrier metal by heat treatment. However, according to heat treatment at low temperature, carbon incorporated from CVD sources into the film is not easily oxidized or removed. Therefore, a problem that leakage current increases arises. As an insulator film of a capacitor, a layered film composed of niobium pentoxide film and a tantalum pentoxide film, or a layered film composed of niobium pentoxide films is used. By the use of the niobium pentoxide film, the dielectric constant of the capacitor can be made high and the crystallization temperature can be made low. By multiple-stage formation of the dielectric film, leakage current can be decreased.

METHOD FOR PRODUCING METAL POWDER FOR DUST CORE AND METHOD FOR MANUFACTURING DUST CORE - A pure iron powder of a diameter of 10 to 500 μm and a purity of 99% by mass or more is heated to a temperature in the range of 600 to 1400° C., and a Si-concentrated layer is formed in regions within a depth of 5 μm from the surfaces of the powder particles by gas-phase reaction at a temperature of that range. The average Si concentration in the regions within this depth is controlled in the range of 0.05% to 2% by mass. Thus, a dust core metal powder enhancing the adhesion of insulating material to the particle without degrading compressibility is produced. The resulting dust core maintains a high saturation magnetic flux density and exhibits a low iron loss.
